CSC RX4 Shift Lever / Gear Shifter - Z434-103
Replacement gearshift lever for the CSC RX4. CSC parts documentation identifies Z434-103 as the RX4 shift lever, foot-controls diagram callout #4. The lever mounts directly to the motorcycle's external splined shift shaft using a split clamp and retaining bolt.

RX3 Compatibility
A mechanic confirmed that this lever will mount to and function on a CSC RX3. However, the Z434-103 lever is a different size and geometry from the stock RX3 shift lever. It should therefore be treated as a functional cross-model option rather than an OEM-equivalent RX3 replacement.
Fitment Note
The RX4 is the confirmed OEM application. For any other motorcycle or engine application, do not assume fitment from the approximately 11 mm shaft size alone. The spline count and spline profile have not been verified, and lever length, offset and geometry can affect operation and rider clearance.
